How do you feed a snail in a tank that has no algae?

Snails are small inverts and do not need to eat much. They are scavengers and will eat algae, and any other small things they can find your fish tank. Snails are a great edition to any tank and the need little if any care!

You can supplement their diet with algae wafers, and small pieces of blanched zucchini and lettuce. Very minimally.
